these two sections.

Today we will be reading pages

Pages 8–11 (Early Uses of Water
Power and The Waterwheel)

Page 8, after: By using water power,
the work done by a person or animal
was reduced.

We are going to see that dates are
reported as BCE or CE. BCE means
Before the Common Era and CE
means Common Era. You can think
of it as a giant number line, with
BCE as the negative numbers,
moving to CE. The only problem is
that there is no year 0. It goes from
the year 1 BCE to the year
1 CE.
